Impact of complex segmentectomies by video-assisted thoracic surgery on peri-operative outcomes.

ABSTRACT: Background:Pulmonary segmentectomies are generally classified into simple (tri-segmentectomy or lingulectomy as well as apical or basilar segmentectomy) and complex (individual or bi-segmentectomy of the upper, middle and lower lobes). Complex segmentectomies are technically feasible by video-assisted thoracic surgery (VATS) but remain challenging, and reports on post-operative outcomes are scarce. This study analyzes the differences between simple and complex VATS segmentectomy in terms of peri- and post-operative outcomes. Methods:We retrospectively reviewed records of all patients who underwent anatomical pulmonary segmentectomy by VATS from 2014 to 2018 in two university hospitals. Results:A total of 232 patients (114 men; median age 67 years; range, 29-87 years) underwent VATS segmentectomy for primary lung cancer (n=177), metastases (n=26) and benign lesions (n=29). The overall 30-day mortality and morbidity rates were 0.8% and 29.7%, respectively. The re-operation rate was 4.7%. Complex segmentectomy was realized in 111 patients including 86 (77.5%) upper lobe segmentectomies and 44 (39.6%) bi-segmentectomies. There was no statistical difference between complex and simple segmentectomy in terms of operative time (145 vs. 143 min, respectively; P=0.79) and chest tube duration [median: 1 (range, 0-33) vs. 2 (range, 1-19) days, respectively; P=0.95]. Post-operative overall complication rates were similar for both groups (30% vs. 30%, respectively; P=0.99) and were not correlated with the type of segmentectomy. However, complex segmentectomy patients had a shorter length of hospitalization compared to simple segmentectomy patients [median: 5 (range, 1-36) vs. 7 (range, 2-31) days; P=0.026]. Interestingly, complex segmentectomies were realized most frequently 2 years after implementation of VATS segmentectomy (23% vs. 77%; P=0.01). Conclusions:In comparison with simple segmentectomy, complex segmentectomy by VATS seems to present similar post-operative complication rates. Learning curve and progressive increase in acceptance by surgeons seem to be key elements for successful implementation of complex segmentectomies and could explain the shorter length of stay we observed.

Project description:BackgroundVideo-assisted thoracic surgery (VATS) generally involves endotracheal intubation under general anesthesia. However, inevitably, this may cause intubation-related complications and prolong the postoperative recovery process. Gradually, non-intubated video-assisted thoracic surgery (NIVATS) is increasingly being utilized. However, its safety and efficacy remain controversial.MethodsRandomized controlled trials (RCTs) published up to August 2020 were selected from the Cochrane Library, Web of Science, PubMed, Embase, and ClinicalTrials.gov databases and included in this study according to the inclusion criteria. Two reviewers screened these RCTs and independently extracted the relevant data. After assessing the risk of bias in these RCTs, a meta-analysis was performed using Review Manager 5.3. Pooled data were meta-analyzed using a random-effects model.ResultsMeta-analysis data demonstrated that the mean difference (MD) in the length of hospital stay between non-intubated patients and intubated patients was -1.41 days, with a 95% confidence interval (CI) of -2.47 to -0.34 (P=0.01). The visual analogue scale (VAS) score between the two groups showed a MD of -0.34 (95% CI: -0.58 to -0.10; P=0.006). Patients who underwent NIVATS presented with lower rates of overall complications [odds ratio (OR) 0.41; 95% CI: 0.25 to 0.67; P=0.0004], air leak (OR 0.45; 95% CI: 0.24 to 0.87; P=0.02), pharyngeal discomfort (OR 0.08; 95% CI: 0.04 to 0.17; P<0.00001), hoarseness (OR 0.06; 95% CI: 0.02 to 0.21; P<0.00001), and gastrointestinal reactions (OR 0.23; 95% CI: 0.10 to 0.53; P=0.0005) compared to intubated patients. The anesthesia satisfaction scores in the NIVATS group were significantly higher than those of the VATS group (MD 0.50; 95% CI: 0.12 to 0.88; P=0.009). However, there were no statistically significant differences in the length of operation time (MD 0.90 hours; 95% CI: -0.23 to 2.03; P=0.12) and surgical field satisfaction (1 point) (OR 0.73; 95% CI: 0.34 to 1.59; P=0.43) between the two groups.ConclusionsNIVATS is a safe and feasible form of intervention that can reduce the postoperative pain and complications of various systems and shorten hospital stay duration without prolonging the operation time.

Project description:BackgroundWith advances in thoracoscopic surgical instruments and techniques, subxiphoid video-assisted thoracic surgery (S-VATS) has become the main approach for anterior mediastinal tumor resection under thoracoscopy. However, the drawbacks of S-VATS, including it being a relatively unfixed surgical procedure, make it complicated and difficult for unexperienced surgeons to master.MethodsThis study retrospectively reviewed and analyzed consecutive patients with anterior mediastinal tumor or myasthenia gravis (MG) who underwent S-VATS at the Fujian Medical University Union Hospital, China, between March 2015 and April 2019.Patients were divided into the conventional group and the "four-zone one-way" group. Intraoperative and postoperative variables were compared between the groups. Cumulative sum (CUSUM) analysis was applied to determine the operation time (OT)-learning curve of the S-VATS "four-zone one-way" method.ResultsA total of 82 patients were included in this analysis, of which, 40 patients underwent the conventional method of S-VATS and 42 patients underwent the "four-zone one-way" method. Patients in the "four-zone one-way" group had significantly shorter OT (138.50±29.43 and 118.00±28.18 minutes, respectively; P=0.002) and significantly less blood loss (36.00±20.16 and 23.92±14.96 mL, respectively; P=0.003) compared with patients in the conventional group. Our data indicated that there was no difference of the efficacy of MG treatment between the 2 groups. The difference in the preoperative and postoperative quantitative MG scoring system score (QMG-score) and the dose reduction of cholinesterase inhibitors was comparable between patients in the 2 groups. According to the CUSUM analysis curve, after a steady improvement over phase I (cases 1-12 for the traditional method and cases 1-5 for the "four-zone one-way" method), the surgical procedure could be mastered. Phase III occurred after case 26 in the traditional group and case 28 in the "four-zone one-way" group, and is characterized by rapid improvements.ConclusionsCompared with the conventional method of S-VATS, the "four-zone one-way" method significantly decreased OT and estimated blood loss. These results demonstrated the feasibility and safety of the "four-zone one-way" method of S-VATS.
